What is prosthodontics?
|
Restoration of natural teeth and/or the replacement of missing teeth and contiguous oral and maxillofacial tissues w/artificial substitutes
|
|
|
What are the branches of prosthodontics?
|
1. Fixed
2. Removable 3. Maxillofacial |
|
|
What is the branch of prosthodontics concerned w/the replacement and/or restoration of teeth by artificial substitutes that are not readily removed from the mouth
|
Fixed prosthodontics
|
|
|
What are 4 examples of fixed prosthodontics?
|
1. Partial veneer
2. Single crown 3. Fixed partial denture 4. Implant restoration |
|
|
What are some restorations that restore all but one coronal surface of a tooth?
|
1. 3/4 crown
2. proximal 1/2 crown 3. 7/8 crown 4. inlay 5. onlay |
|
|
What is a tooth portion of a tooth, or that portion of a dental implant that serves to support and/or retain a prosthesis
|
Abutment
(synonomous with the prep) |
|
|
What is the junction of the cut and uncut portion of the prepared tooth, referred to as
|
Finish Line
|
|
|
What is that portion of a fixed partial denture that unites the abutment to the remainder of the restoration
|
Retainer
(casting or restoration) |
|
|
What is the circumferential terminal end of the restoration?
|
Margin of the restoration
|
|
|
What is an artificial tooth on a fixed partial denture that replaces a missing natural tooth, restores its functions, and fills the edentulous space?
|
Pontic
|
|
|
What is the portion of the fixed partial denture that unites the retainer and the pontic?
|
Connector
|
|
|
What governs tooth preparations?
|
1. Preservation of tooth structure
2. Retention and resistance form 3. Structural durability of the restoration 4. Marginal integrity 5. Preservation of the periodontium |
|
|
What term refers to preventing removal of the restoration along the long axis of the tooth preparation & essential element is two opposing vertical surfaces in the same preparation
|
Retention
|
|
|
What prevents dislogement of the restoration by forces directed in an apical or oblique direction and prevents any movement of the restoration under occlusal forces?
|
Resistance
|
|
|
What is it called when the axial wall must converge toward the occlusal (6-16 degrees)
|
Taper
|
|
|
What term defines:
Retention is improved when there is only one path of insertion for that restoration Limits displacement in a horizontal or torque force (grooves or proximal box) |
Freedom of displacement
|
|
|
What is vital to both retention and resistance form
Relates to the O/G dimension of the preparation Restoration success is governed by a force capable of iinterfering with the arc of the casting pivoting about a point along the opposite side of the preparation |
Length
|
|
|
What is the imaginary line along which the restoration will be placed onto or removed from the preparation
Viewed with one eye from a distance of 12 inches |
Path of insertion
|
|
|
Relates to the amount of restorative material necessary for that restoration to sustain occlusal loads and patient function
Limited to the confines of the tooth preparation |
Structural durability
|
|
|
Intimate adaptation of the finish line of the prepared tooth with the margin of the restoration
Configurations: Chamfer, shoulder |
Marginal Integrity
|
|
|
Definitive restoration should not interfere with periodontal health
Finish line placement should be in a cleansable region |
Preservation of the periodontium
|
|
|
What perspective should the prep be viewed from when you are aligning your path of insertion?
|
Single eye vision from the MD & FL perspectives
|
